Wii people really need to get over this. You can't put it on the Wii any more than you could do RE4 on the N64. Now, a RE 4.5....
As for those comlaining about the similarities to RE4... in terms of gameplay, that's really not a bad thing. In terms of monsters/baddies... this is a continuation of the same story, so overlap is expected (just as there were Zombies in all the original REs), and I don't expect them to reveal anything new this early. This is there just to whet the appetite.
